Location Estimation in a 3D Environment using RFID Tags

RFID tag location in a 3D environment is
investigated. The location of the tag with unknown
coordinates can be estimated with certain accuracy.
However, accuracy can be improved using the knowledge
based on measurement of additional reference tags
with known location. This book studies the
mathematical formulation and practical realization of
location sensing using RFID tags.

Deviating from the standard use of RFID technology
which employs one tag reader to identify presence of
tag, multiple tag reader with known location are used
to estimate the physical location of an individual
tag, with/without the help of few reference tag with
known location. Additionally, concept of
trilateration has also been extended for tracking the
tag on unknown location without use of reference
tags. It was demonstrated that both approaches were
proved to be cost-effective technique and estimation
of the location of a specific tag has been achieve
with sufficient accuracy.

Born in India and lived in Delhi,I was obsessed with Electronics
all of my life and chose to study it.An Engineer from Haryana
came to pursue MS in Telecom from NJIT,NJ where I
wrote this Thesis on RFID during 2006.I hope this book helps
further students and create an impact on mankind in a positive
manner. "Life teaches you everyday, Utilize it".
